Miley Cyrus has had secret boyfriend for nine months

Cyrus has been dating her "Bangerz" producer Mike Will Made-It for the past nine months, multiple sources told Us Weekly.

"Everybody in her circle knows they've been together this whole time," a source close to Cyrus reportedly said. The 21-year-old started seeing the 25-year-old producer soon after splitting from Liam Hemsworth in September.

Another insider told the magazine the pair has become "pretty serious." Made-It even won over Cyrus' mother, Tish.

"Tish says he's part of the family," the insider said.

Of course he is.

While on tour, Cyrus has made a point to stay connected to Made-It. Despite not always being in the same city, the couple makes sure to "talk and text all day, every day," the source says.
